I am Chris Hogg, a Health 2.0 advocate, tech enthusiast, and researcher/analyst of all things healthcare. I like to think about the changing healthcare landscape, the value and utility of health data, the changing relationship between physician and patient and the impact of technology on behavioral change. Currently, I am a commercial strategist for a major biotech company in the Bay Area. I am also a husband and proud new father.

um… the api and everything already has been done. Geez, I’ve been using it for years.
http://en.wikipedia.org/wiki/Continuity_of_Care_Record
Here’s the implementation:
take each of the sections, ‘demographics’, ‘surgeries’, ‘medications’, ..whatever
make each an html section marker
put the relevant info into each.
This allows personal health records readable in abu dabee to Zanzibar.
It is parsible. I have programs to give a nice front end for it, to give the current best practice guidelines based on the medical information, and ability to fill out a bunch of forms using the info. (they were built from a Mad libs program source code). Interested, I can send you all the programs, etc, etc (the lot of everything is under 10k in size)
